DETAILED DESCRIPTION

The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

A system or method, described herein, may be used to enhance search engine results by enabling search engine results to include scored sitelinks. For example, a sitelink management system may receive a request for sitelinks corresponding to a particular document (e.g., a web page). A sitelink, as described herein, may include a hyperlink within a search result document that is based on, or corresponds to, a hyperlink within a document. A sitelink may include a direct link to some part of the document, a direct link to some content of the document, etc. The sitelink management system may identify hyperlinks corresponding to the document, determine visual locations corresponding to the hyperlinks, and/or score the hyperlinks based on the visual locations. In one implementations, a visual location may include information describing a position of a hyperlink as represented by a document object model (DOM) corresponding to a document that includes the hyperlink, and/or information describing a position of the hyperlink when a document that includes the hyperlink is displayed within a web browser. The sitelink management system may also, or alternatively, provide sitelinks in accordance with the score of each hyperlink.

Since sitelinks may be included in a search engine result, scoring sitelinks according to visual locations and providing the sitelinks according to the score of each sitelink may enable the search engine result to not only include a hyperlink to a document, but also to include sitelinks corresponding to the most visually and/or functionally significant hyperlinks within the document. Accordingly, a system and/or method, as described herein, may be used to enhance search engine results corresponding to a document with one or more sitelinks to improve a user's search experience.

The concepts described herein may be applied to sets of documents. In one implementation, the documents may be images, such as images indexed by an image search engine. More generally, a document may be broadly interpreted to include any machine-readable and machine-storable work product. A document may include, for example, an e-mail, a web site, a file, a combination of files, one or more files with embedded links to other files, a news group posting, a news article, a blog, a business listing, an electronic version of printed text, a web advertisement, etc. In the context of the Internet, a common document is a web page. Documents often include textual information and may include embedded information, such as meta information, images, hyperlinks, etc., and/or embedded instructions, such as JavaScript, etc. A “link” or “hyperlink,” as the terms are used herein, are to be broadly interpreted to include any reference to/from a document from/to another document or another part of the same document.

FIG. 1 is a diagram of an example environment 100 in which systems and/or methods described herein may be implemented. As depicted, environment 100 may include client systems 110-1, . . . , 110-N (where N≧1) (hereinafter referred to collectively as “client systems 110,” and individually as “client system 110”), network 120, search engine system 130, and sitelink management system 140.

The request may originate from a user or operator of sitelink management system 140, client system 110, search engine system 130, or another type of system or device capable of communicating the request. Additionally, or alternatively, the request may be part of an automated process or application corresponding to executing a search engine query, a document indexing task, or another type of automated process.

Hyperlinks within the document are identified (block 420). For example, sitelink management system 140 may identify hyperlinks within the document. In one example, sitelink management system 140 may execute an operation, process, or application, such as a parse operation, process, or application to identify the sitelinks within the document and/or parse the document to locate tags (e.g., hyper text markup language (HTML) tags) corresponding to hyperlinks. In one possible implementation, sitelink management system 140 may analyze the parsed document with a pattern recognition (e.g., character recognition) operation, process, or application to identify the sitelinks within the document and/or the tags corresponding to hyperlinks.

Visual locations of the hyperlinks within the web page document are determined (block 430). For example, sitelink management system 140 may determine the visual location corresponding to each hyperlink within the document. As mentioned above, a visual location, as described herein, may include information describing a position of a hyperlink element within a DOM corresponding to a document, and/or information describing a position of the hyperlink when a document, that includes the hyperlink, is displayed within a web browser or another type of application.

The hyperlinks are scored based on the visual locations of the hyperlinks (block 440). For example, sitelink management system 140 may score the hyperlinks based on visual locations corresponding to the hyperlinks. In one example, sitelink management system 140 may score the hyperlinks based on one or more hyperlink analysis operations or processes executed by sitelink management system 140. For example, sitelink management system 140 may analyze the visual location of a hyperlink, as well as the visual location of other hyperlink within the document, to determine whether the hyperlink is positioned or arranged within the document in a manner that suggests that the hyperlink is a significant feature of the document.

FIG. 5 is a diagram of an example document 500 according to one or more implementations described herein. As depicted, document 500 may include images 510, text 520, and hyperlinks 530-1, 530-2, . . . , 530-15. While FIG. 5 shows a particular number and arrangement of features (e.g., images 510, text 520, and hyperlinks 530), in alternative implementations, an example document may include additional features, fewer features, different features, or differently arranged features than those depicted in FIG. 5.

As mentioned above, sitelink management system 140 may identify hyperlinks 530 within document 500, determine the visual locations of hyperlinks 530 within document 500, and score hyperlinks 530 based on visual locations corresponding to hyperlinks 530. In one example, sitelink management system 140 may score hyperlinks 530 by identifying different hyperlink groups within document 500 and identifying which hyperlink group seems to be the most significant with respect to document 500.

For instance, in example document 500, sitelink management system 140 may identify or otherwise define one hyperlink group as hyperlinks 530-1 through 530-5 since each of hyperlinks 530-1 and 530-5 appear in document 500 as a sequence of contiguous hyperlinks 530 (or hyperlinks 530 appearing together on an X-axis or a Y-axis). Sitelink management system 140 may identify another hyperlink group as hyperlinks 530-6 through 530-8 since hyperlinks 530-6 through 530-8 appear in document 500 as a sequence of continuous hyperlinks 530 (or hyperlinks 530 appearing together on an X-axis or a Y-axis). Sitelink management system 140 may identify another hyperlink group as hyperlinks 530-9 through 530-11, and another hyperlink group as hyperlinks 530-12 through 530-15, for similar reasons. Hyperlink management system 140 may determine that the hyperlink group corresponding to hyperlinks 530-1 through 530-5 is the most significant to document 500 since the hyperlink group corresponding to hyperlinks 530-1 through 530-5 includes the largest quantity hyperlinks 530 and/or appear closest to the top of document 500.

Additionally, or alternatively, sitelink management system 140 may determine the importance or significance of each hyperlink 530 within a hyperlink group. For example, referring to the hyperlink group that includes hyperlink 530-1 through hyperlink 530-5, sitelink management system 140 may determine that hyperlink 530-1 is the most significant of the hyperlink group because of the visual location of hyperlink 530-1. For similar reasons, sitelink management system 140 may determine that hyperlink 530-5 is the least significant of the hyperlink group. As such, sitelink management system 140 may score hyperlinks 530 based on a visual location corresponding to each hyperlink 530.

FIG. 6 is a diagram of an example of a DOM 600 according to one or more implementations described herein. As depicted in FIG. 6, DOM 600 may include elements 610-1 through 610-4 and hyperlink elements 620-1 through 620-8. Elements 610 may include any type of DOM element (e.g., a TITLE element, a HEADER element, etc.).

Hyperlink elements 620 may include DOM elements corresponding to one or more hyperlinks 530 of FIG. 5. For instance, hyperlink elements 620-1 through 620-5 may correspond to hyperlinks 530-1 through 530-5, respectively. However, for simplicity, only some of hyperlinks 530 are represented by hyperlink elements 620 in FIG. 6. In addition, while FIG. 6 shows a particular number and arrangement of DOM features (e.g., elements 610 and hyperlink elements 620), in alternative implementations, a DOM may include additional elements, fewer elements, different elements, or differently arranged elements than those depicted in FIG. 6.

As mentioned above, sitelink management system 140 may also, or alternatively, identify visual locations corresponding to hyperlinks within document 500 by obtaining software code corresponding to document 500 and using the software code to create DOM 600. Sitelink management system 140 may define the visual location of hyperlink 530 based on a position of a corresponding hyperlink element 620 in DOM 600. For instance, sitelink management system 140 may identify an X-coordinate and/or a Y-coordinate corresponding to each hyperlink element 620 and use the X-coordinate and/or Y-coordinate to identify or define visual locations, in addition to scoring one or more hyperlinks 530 corresponding to hyperlink element 620.

Additionally, or alternatively, sitelink management system 140 may identify or define hyperlink groups based on two or more hyperlink elements 620 corresponding to the same X-coordinate or Y-coordinate. In addition, sitelink management system 140 may identify or define hyperlink groups based on an ancestor DOM element (e.g., a parent DOM element, a grandparent DOM element, etc.) corresponding to each hyperlink element 620. For instance, if hyperlink element 620-1 through hyperlink element 620-8 were all positioned along the same X-coordinate or Y-coordinate, sitelink management system 140 may determine, based on ancestor DOM elements 610-2 and 610-4, that hyperlink elements 620-1 through 620-5 correspond to a different hyperlink group than hyperlink elements 620-6 through 620-8. Ancestor DOM elements may also, or alternatively, be used to infer the manner and/or general location that one or more hyperlinks 530 may be presented when document 500 is displayed in a web browser. Accordingly, sitelink management system 140 may use DOM technologies to identify visual locations corresponding to hyperlinks 530 and/or score hyperlinks 530 based on the visual locations, which may include identifying hyperlink groups, scoring hyperlink groups, etc.

Returning now to FIG. 4, process 400 may include providing sitelinks, corresponding to hyperlinks 530, according to the score of each hyperlink 530 (block 450). For example, sitelink management system 140 may provide sitelinks, corresponding to hyperlinks 530, according to the score of each hyperlink 530. In some implementations, providing sitelinks may include sitelink management system 140 storing the sitelinks for later use, Additionally, or alternatively, sitelink management system 140 may provide sitelinks to search engine system 130 so that, for example, search engine system 130 may include one or more of the sitelinks in a search result document that provides search engine results. In some implementations, sitelink management system 140 may provide the sitelinks in accordance with one or more rules or instructions, such as a limit to the quantity of sitelinks that may be provided, a constraint on the types of sitelinks that may be provided (e.g., sitelinks that do not exceed a particular length), etc.

While FIG. 4 shows a flowchart diagram of an example process 400 for providing sitelinks based on visual location, in other implementations, a process for providing sitelinks may include fewer operations, different operations, differently arranged operations, or additional operations than depicted in FIG. 4.

For example, the visual location of a hyperlink may be one factor of several factors used to score the hyperlink. An example of another factor may include a click-through rate corresponding to the hyperlink. In addition, in some implementations, one type of factor may be given more consideration than another type factor. For instance, a click-through rate corresponding to a particular hyperlink may have a greater impact on scoring the hyperlink than other factors.

FIG. 7 is a diagram of an example search result document 700 according to one or more implementations described herein. As depicted, search result document 700 may include a search parameters text box 710, a search command button 720, search engine results 730, and a document navigation tool 740. While FIG. 7 shows a particular number and arrangement of document objects (e.g., search parameters text box 710, search command button 720, search engine results 730, and document navigation tool 740), in alternative implementations, search result document 700 may include additional document objects, fewer document objects, different document objects, or differently arranged document objects than those depicted.

Search parameters text box 710 may provide a location for a user to input one or more search parameters (e.g., a letter, a number, a symbol, etc.), and search command button 720 may enable the user to cause a search query to be executed, based on the one or more search parameters, and search engine results 730 to be provided that are relevant to the one or more search parameters. Since search queries resulting in a large quantity of search engine results 730 may cause search engine results 730 to be displayed in multiple search result documents 700, document navigation tool 740 may enable the user to navigate between the search result documents 700 containing search engine results 730.

As depicted in FIG. 7, search engine results 730 may include one or more of a variety of information. For example, search engine results 730-1, 730-2, 730-3, and 730-4 each include a document title (which may also be a hyperlink to a corresponding document 500), a document description, and/or a document address, such as a uniform resource locator (URL). In addition, search engine results 730-1 and 730-2 each include sitelinks 735, which may corresponds to high-score hyperlinks 530 of document 500. As such, sitelink management system 140 may identify hyperlinks 530 within document 500 of FIG. 5, determine a visual location of hyperlinks 530 within document 500, score sitelinks 530 based on the visual locations of hyperlinks 530, and provide, cause, or otherwise enable sitelinks 530 to be provided in accordance with the score of each hyperlink 530. Providing sitelinks 735 based on the score of corresponding hyperlinks 530 may help ensure that the most significant hyperlinks 530 of document 500 are included in a search result that corresponds to document 500.

FIG. 8 is a diagram of example functional components of sitelink management system 140 according to one or more implementations described herein. As depicted in FIG. 8, sitelink management system 140 may be associated with a web 810 and may include a parser 820, a document renderer 830, a DOM tree 840, existing sitelinks 850, and a sitelink generator 860. Web 810 may correspond to network 120 (e.g., the Internet). Existing sitelinks 850 may be provided by search engine system 130 and/or sitelink management system 140.

Parser 820 may enable sitelink management system 140 to access a particular document (e.g., document 500) via web 810 and/or scan (e.g., “parse”) the document 500 to identify hyperlinks within the document. In scenarios where a copy of the document is available in a data repository, sitelink management system 140 may also, or alternatively, identify hyperlinks within the document based on the copy of the document (e.g., without the parser functionality). As such, sitelink management system 140 may be capable of identifying sitelinks within a document in one or more ways.

Document renderer 830 may enable sitelink management system 140 to render the document in a browser application. The browser application may be capable of computing or otherwise creating DOM tree 840 corresponding to the document, where DOM tree nodes correspond to hyperlinks and include coordinates identifying a visual location (e.g., an X coordinate and a Y coordinate) corresponding to each hyperlink. The browser application may or may not be a browser application with a user interface component. Accordingly, sitelink management system 140 may be capable of implementing browser applications and/or DOM trees to determine visual locations corresponding to hyperlinks within a document.

Sitelink generator 860 may enable sitelink management system 140 to score sitelinks 530 based on a visual location corresponding to each hyperlink 530. As discussed above, this may include, for example, identifying hyperlink groups, determining a group score corresponding to each hyperlink group, and/or determining a hyperlink score corresponding to each hyperlink 530 (e.g., each hyperlink 530 in a hyperlink group). A group score and/or a hyperlink score may be determined in one or more of a variety of ways. For instance, as discussed above, a group score may be determined based on a quantity of hyperlinks 530 corresponding to a particular hyperlink group, relative to a quantity of hyperlinks 530 corresponding to another hyperlink group within document 500. A hyperlink score may be determined based on, for example, a visual location corresponding to a particular hyperlink 530 relative to the visual locations corresponding to one or more other hyperlinks 530 within document 500. In one example, once sitelink management system 140 identifies a particular hyperlink group as have a higher score than another hyperlink group, sitelink management system 140 may disregard one or more hyperlinks 530 corresponding to the lower-score hyperlink group.

As depicted in FIG. 8, the document may already be associated with existing sitelinks 850. In such scenarios, sitelink management system 140 may determine whether existing sitelinks 850 are consistent with the hyperlinks identified and scored by sitelink management system 140. In some implementations, existing sitelinks 850 that are not consistent with hyperlinks 530 identified and scored by sitelink management system 140 may be deleted, disassociated from the document, or otherwise handled so that the inconsistent sitelinks are not displayed in a corresponding search engine result 730 or do not take score over the sitelinks identified and scored by sitelink management system 140.

In addition to the functionality described above, the functional components of sitelink management system 140 may also, or alternatively, provide functionality as described elsewhere in this description. Further, while FIG. 8 shows a particular number and arrangement of functional components, in alternative implementations, sitelink management system 140 may include additional functional components, fewer functional components, different functional components, or differently arranged functional components than those depicted.

In some implementations, one or more of the outputs discussed above may be stored at any point during the overall sitelink scoring/management process. For instance, a DOM tree, rendered document, pared output, etc., may be stored by sitelink management system 140 and/or by another system.

Accordingly, systems and devices, described herein, may be used to enhance the information provided in search engine results. For example, sitelink management system 140 may receive a request for sitelinks corresponding to a document. Sitelink management system 140 may scan the document to identify hyperlinks included within the document and determine visual locations corresponding the hyperlinks within the document. Sitelink management system 140 may score the hyperlinks based on the visual location corresponding to each of the hyperlinks and provide sitelinks, corresponding to the hyperlinks, in accordance with the score of each hyperlink. Scoring hyperlinks according to visual location and providing sitelinks according to the score of corresponding hyperlinks may enable a search engine result to not only include hyperlinks to documents, but also to include the most visually significant sitelinks within the document. Accordingly, systems and devices, as described herein, may be used to enhance search engine results by including scored sitelinks in search engine results.
